MPEG DASH provides formats that are suitable to stream segmented media content over HTTP. DASH clients follow a client-pull paradigm by adapting their requests based on the available bandwidth and other local resources. This has proven to be easier to deploy over CDN infrastructure than server-push technologies. However, this decentralised nature introduces new challenges such as offering a consistent and higher quality of service for premium users. MPEG is addressing this issue in the to-be-published new MPEG DASH part 5, Server and Network-assisted DASH (SAND). The key features of SAND are asynchronous network-to-client and network-to-network communication of quality-related assisting information. In addition, DASH-IF is further defining interoperable guidelines to optimise SAND deployments in a variety of environments: home network, over-the-top, etc. MPEG is expected to publish SAND by end of 2016 while DASH-IF aims for the course of 2017.
